A longitudinal fin of rectangular profile is used to enhance
heat removal from a wall maintained at 450 F. The fin is made of carbon steel.
The fin is exposed to a convection boundary. Find a) temperatures at the tip of
the fin and b) the rate of heat loss from the fin, c) fin effectiveness,
defined as the rate of heat loss from the fin to the rate of heat loss without
the fin, and d) fin efficiency, defined as the rate of heat loss from the fin
to the rate of heat loss from the fin if the entire fin were at the base
temperature. Fin length = 1 in, fin thickness = 1/8 in, fin width = 6 in,
